Abstract
According to E. G. Lorenzen, the international theory of the conflict of laws rests almost wholly on fiction. The discipline of conflict of laws is created by a huge number of national internal laws and quite a large number of international instruments. Concepts used there are interpreted in many ways illustrating the variety of legal solutions and values. Some of the instruments facilitating the correct application of law are unregulated. One of them is qualification, which starts the process of indication and application of the proper law and assists in its completion.
